Other Information:

Thermistor: BetaTherm - Micro-BetaCHIP Probe 10K3MCD1 0.018" diameter, 10Kohms at 25 C

Probe:

stainless steel sheath 0.063 inch (0.16 cm) diameter, 2.3 inch (5.84 cm) length overmolded joint 0.40 inch (1.02 cm) diameter, 1.67 inch (4.24 cm) length

Cable: Santoprene 0.220 inch diameter

Cable/probe connection: "ATUM" heat shrink, "Macromelt" overmolded joint

Weight: 0.2 lbs/10 1/2 ft cable

NOTE The black outer jacket of the cable is Santoprene® rubber. This compound was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.
